Overview
Not an electronic smart lock, the Lockey deadbolt opens with a mechanical push button code and needs no batteries or wiring. Its marine grade finish suits coastal and boat house doors, and the deadbolt length adjusts to the door.
No batteries means no lockouts from dead cells and no electronics to corrode. The listing is minimal, with no door thickness range, code count or warranty given.
Who it's for
Owners of beach houses, boat docks and outbuildings who want keyless entry without electronics will use it. Those wanting phone control or guest codes need a smart lock.
Pros and cons
- No batteries to replace
- Marine grade finish
- Code can be reprogrammed
- Door fit range and warranty not listed
- No remote or guest codes
Performance notes
Security depends on the mechanical combination, which works regardless of power or weather. The marine grade finish resists salt air corrosion. Code changes are made mechanically rather than through an app.
